Non-intrusive load monitoring apparatus and method

摘要

A non-intrusive load monitoring (NILM) apparatus and method which detect state change of a load using a power factor of power consumption as a feature or detect sate change of a load using both a power factor and apparent power, and identify the load using the superposition theory. The NILM apparatus includes a sensor unit to collect information regarding power consumption of home appliances, and a controller detecting power consumption-related events occurring in the home appliances based on power factor information among the power consumption information collected by the sensor unit.
